A new core drilled at Nørrekær Enge, Løgstør, Denmark shows terrestrial lake and bog sediments lying beneath 10 m of marine sediments. Pollen analysis, 14C dating and sedimentary observations show that these sediments relate to an ancient lake basin which was flooded when the the rising sea levels reached 8.0 m b.s.l. This new study has allowed a review of previous data relating to shoreline displacement from the Limfjord Region of northern Jutland, Denmark. Here we present a new shoreline displacement curve spanning the period between c. 11 700 and 7 700 cal. a BP and built upon the Nørrekær Enge data and data from 7 other boreholes and excavations from the Limfjord region. A previous shoreline displacement curve for this region suggested a very rapid relative sea level rise of 3 to 5 m 100 a-1 whereas this new curve suggests a much slower rise of around 1 m 100 a-1, similar to global rates.
